' 7 Application filed September 8, 1925. Serial M55 3.)

- -This invention, as indicated, relates to a plural liquid distributing system and an automatically operated distributing valve for,

use therewith. The 'sub ect matter in an improvement over my Patent No.

1,490,179, granted April 15, 1924, wherein a having a plurality of compartments instead:

of a single compartment casing, one otsaid' compartments serving as the inlet chamber of either of the fluids to be pumped, for ex ample hard or soft water, a central chamber serving as a governor chamber and the other chamber servingas the liquid distributing means to the lines leading to the respective receiving tanks. 1

Another objectof the invention is the provision of multiple chambers and separate valves for each of the inlet and discharge V I i i to provide continuous flow. Thelinletand lines.

A further object of the invention is to provvide a positive closing of each port ndependently of the associated ports.

Another object of the invention 1s to provide for a two stage operation of the governor'valves so thatthe pump may empty out the water of the character in transit before shifting to the water supply'of the other character.

A further object of the, invention is to '1m- I prove the mechanical construction of the'ap paratus whereby. the small tubular passage 40, ways are dispensed with and straight pas-' V sage waysare provided directly between the several chambers of the/casing,

A still further object 'of the invention is the provision of a check valve for each suction line, thus preventing accidental siphoning of water from one source, of supply to the other, or from ahigher to a lower water level. p v I p It is also in View that in place ofdelaying of the water of the kind previously operated on before commencing on the iwater'fsupply of the other character, thata complete discharge of said water to a waste line may be l adopted.

this application v is the valve action until the 'pump can clear 0 her and further objects of thefinvention will appe'ar in the course, of the following." A

description. To the accomplishment o fthe foregoing and related ends, said inventionf then, consists of the means hereinafter fully described and particularly pointed' out inf the claims.

In the lower-wall of the inter mediate chamber at a central point, a" passage way 37 between sai'd intermediate chamber-and. the lower chamber is provided, and similar passage ways 38,39 are provided through the: bottom wall of said intermediate chamber at points adjacent the end wallsof the casing. A pair of' similar passage ways41, 42 are provided between the intermediate chamber and the upper chamber. Said last mentioned. passage ways are spaced a, greater distance inwardly from the end-walls, of said casing than the passage ways38, 39. for a purpose which. will presentl' appear. The upper Wttlli of the intermec iate chamber is. also provided with inclined passage ways 43,. 44, which are shown in Fig. 3. and may each be formed by drilling angularl'y disposed holes 45,. 46 through the upper walls of, said. intermediate chamber, said holes meeting.

Upon the reduced'central portion of the shaft, a pair of valve disks, 71', 72: are; slidingly mounted. Said valve disks each comprise a metal plate against the innerface of which a rubber disk is secured. Said valve disks are adapted to engage respectively against the outer faces the described and is provided atri-ts ends with working heads 82, 83, against the outer faces of which outwardly turned cup washers 84,

respectively are positioned, said shaft and the working heads thereon comprising the governor valve mechanism of the apparatus.

Inaddition to the structural elements heretofore describcchthe apparatus will be pro videdwiath standard means for automatically controlling the pumping unit, Such control devices are well known in, the art, and serve; to cut off the pumping; unit when bothv tanks are full, and serve to start the pumping; unit when the pressure in either of said? tanks falls below: a predetermined. mnount,

The operation of" the apparatus as follows: V

The pressurein the hard water tank. is at all times brought, to bear upon the governor head 82 in theintermediate chamber tl'iro-ugh the passageway 44 andiv the pressure in the soft water tank is also at all. times brought; tobear on. the governor head 83. through. the passageway 43 hen. the pressure in the hard Water. tank. 1

is less than that in the soft water tank. and

thepartsof the distributing; valve are. in: the

position shown/in. Fi 4 of the drawing, if V 3]. and; line 3-intothepump-11, and thencev will be discharged. through the line 4 and.

port 32 into the upper chamber, forcing the disk 71-, to. the left and thence passing through the line 13 into the hard water tanli.

When, the pressure in. the. hard water tank; is relatively.- greater so asto overbalance the pressurefrom the soft water tank, the governor valve will. move to the right, the head, 82 passlng the port 38 and stopping momens tarily. at such pqinhwhile thepressure is-escaplng from behind the governor head 82 through the port 38 and into thedower' chamber, where it operates against the head 52 mov ng the same to the right, andbringing the shoulder of thefenlarg'emcnt 59 tight ly against the'valve disk- 57, thus s'hutting' off the well water from the suction'line and permitting the suction to move the valve 5fl inwardly and thusopening the passage Way for the cistern Water through the li'ne l t to again stops; while pressure on the head 66 in the upper chamber is built up and the valve shaft 61 movesto the right until the shoulder 64 bears against the valve disk 71,

thus closing the wellwater discharge line, and permittlng the cistern water control valve 72 to be forced open, and the cistern water to be supplied to the soft water tank through the line 15. i W

The delayed operation of the several valves just described is intended to permit the pump to empty all of the liquid being handled in order that no mixture of hard and soft water in the tanks will occur, if

such are the fluids being utilized in the systern; With anordina'ryinstallation, it has been found that by allowing aperiodof five seconds between the time of the closing of the suction valve for the hard water and the closing of the discharge valve therefor, the pump will be practically free of the hard water before commencing,to operate upon the soft water supply.

After the valveoperations described have taken place," the governorv head 82 moves further to the right due to the increased pressure thereon until the governor head '83 comes in contact with the end wall 25. Said head 83 is then forced past the valve ports 42 and 39, and the pump suction is then exerted through the ports 37 and 42, relieving all back pressure on the heads 53 and 66.

When the pressure in the soft water tank reaches a predetermined amount, preferably 8 pounds more than the pressure in the hard water tank, the governor heads 83 and 82 will be moved to the left and the various valves will be shifted so as to resume their original position or the positions disclosed in Fig. 4:. The springs 7.3 and 74 serve to normally keep the disk valves against their seats, which prevents any surging of water from the higher to the lower pressure tank. When the automatic control of the pump starts the mechanism, the force of the liquid entering through the discharge port 32 will be suflicient to operate the valve 71. It is to be noted that the disk valves 71 and 72 are loo'sely'engaged upon the shaft 61, which allows a slight amount of water to pass said valve disks and thus, at all times, maintain enough pressure on the pump valves to prevent their leakage and a constantstarting and stopping of the pump which would follow the failure,tojmaintam such pressure. Such slight leakage through i the valve disk only-takesplace in the valve which is not abutt'edby" eitherof the adja cent shoulders64 and on the shaft 61,in

asmuch as the shoulder makes a ground joint to fit with the adjacent valve plate and prevents the passage-of liquid through the valve: disk engaged thereby. t

The'valvedisks 56" and 57ers also slidably mounted upon the headsupporting" shaft 51' and the spring? 56 bearing theree,

against serves to have said valvedisks function as checkvalves on'both suction lines. This prevents any accidental siphoning action, which experience has shown at'all times occurs between'va cistern'and'a well where the water level in the" well is considerably; lower than the waterlevel in-the cistern; 1n

- the absence of such construction, such action might take place: during the-time of the shiftingiof the valve, particularly* when the pump isidl-e and the pressure inithe tanks change in amount" suflicient toishift the valves'without starting-Lthepuinp. v I
